Hydraulic control is a kind of straight track rail line to straighten the horizontal direction (or bending) of the manual hydraulic special tools. This machine is simple, reliable, straight (or bent) rail satisfactory results, the advantages of wide application. Especially for the 60kg / m, 75 kg / m two heavy rail, the application it is particularly convenient, and can achieve a comprehensive cross-section curved rail, the rail must not produce distortion, is essential for a new type of mechanized track maintenance manual hydraulic machinery .

 Were used hydraulic oil, machine oil No. N15-N32 
 Direct rail is controlled by hydraulic lock hook assembly and the fuselage frame assembly of two parts. Cylinder assembly, the gap adjustment devices are part of the body frame assembly. 
 1. Cylinder assembly from the cylinder, piston, ring, top block, safety valve, return valve and spare oil return valve. 
 2. Valves adjusted before the company, the user may not be arbitrarily transferred. 
 3. Back to the oil valve is a screw through the top tight oil return valve to release the ball to achieve complete occlusion of the oil return valve and open role. 
 4. Spare oil return valve is a valve failure at the back post, you should use, normal operation can not be used. 
 5. Gap adjustment device from the top of the block C, the handle and the limit screws composition. 
 6. Rail straight (or curved) is based on leverage to achieve
